In view of the importance of having inspectors on board foreign
trawlers, every effort should be made by the Mauritanian
Authoritites to improve the present system of inspection (by
ensuring the rotation of inspectors, for example).

When collecting data, countries should not only concentrate
on species of national importance, but should also recognize
international requirements.

Fishing logbooks should be put on all kinds of vessel to
improve the relivaility of statistical data.

For those species for which appropriate data are available,
CRODT should carry out yield per recruit assessments.

The Working Group also recommended that :

all possible efforts should be made to estimate the rates of
discarding in all fisheries where sparids are important.

All possible efforts should be made to improve the species
breakdown in those fisheries where this is not already done.

Gambia, Guinea and Guinea Bissau should try to provide detailed
statistics, broken down by species, and should initiate port
sampling for length frequencies for the most important sparid species. They should also request their foreign partners to
initiate sampling on board their commercial vessels for length
frequencies.

Morocco, for both divisions 34.1.1 and 34.1.3, should initiate
port sampling for length frequencies, should improve the
species breakdown in the statistics and should start fecundity
studies.

Portugal should try to breakdown their statistics by division
and should collect length frequency distributions and other
biological data for the principal sparid species landed.

Spain (Canaries) should collect statistical and biological data,
by species, for at least the most important species landed.

Mauritania, should, for each statistical division, increase
port sampling for length frequencies ; should improve the
species breakdown in the statistics ; and should start fecundity
studies.

Senegal should submit improved historical data, and make every
effort to obtain statistical information for some foreign
fleets.

A future Working Group on sparid stocks should adopt a
multispecies approach to the assessments.

The main recommendations for improvement of biological and statistical
data collection are summarized in Table 74.
